  • Patent number: 10744032
    Abstract: An ophthalmic surgical instrument for fragmenting the lens nucleus of an eye, and method of use thereof. The instrument includes an elongated handle portion, a tubular head portion at the handle portion distal end, at least three prongs with cutting tips, and a holding ring. The prongs are selectively retractable into and deployable from the head portion. The holding ring selectively contracts and expands to adjust the deployment width of the prongs. The instrument is inserted toward the eye lens through a corneal incision, while the head portion is opened to deploy the prongs to slide over and grasp onto the lens nucleus at a posterior position thereof. The instrument is then withdrawn toward the eye lens anterior while the head portion is closed to retract the prongs, such that the prong cutting tips cut along the lens nucleus, so as to fragment the lens nucleus into multiple segments.

The connector member can comprise a resilient material such that an external force may be applied to the suturing head and move the suturing head from a biased orientation (e.g., linear) to an unbiased orientation (e.g., non-linear). Once the external force is removed, the resiliency of the connector member allows the suturing head to return from the unbiased orientation to the biased orientation. Therefore, a user may adjust the shape of the instrument by applying or removing an external force on the suturing head.

  • Patent number: 9486238
    Abstract: A minimally invasive surgical assembly broadly includes an outer tube which has an outer diameter of 3.0 mm or smaller, and a coaxial surgical instrument having a shaft which extends through the outer hollow tube. The coaxial surgical instrument includes end effectors at the end of the shaft. The end effectors include spring arms and wire frame clamp elements defining fenestrations. The spring arms are biased to an open position such that when the end effectors of the surgical instrument extend out of the outer tube they open, and they are closed by relative movement of the outer tube over them. The wire frame clamp elements are biased to an open position such that when they extend out of the outer tube they open and they are closed by relative movement of the outer tube over them.

  • Patent number: 9451947
    Abstract: A modification to a standard needle driver in the form of a deployable and retractable projection at the working end of the needle driver with which the operator can control the suture in order to facilitate tying a knot in the suture. This modification solves the difficult problem of controlling the suture during the rate-limiting step of knot tying allowing for faster, easier knot tying in laparoscopic and single port surgery.

  • Patent number: 9351710
    Abstract: Among other things, there are disclosed embodiments of full-core biopsy needles having an outer needle component and a middle cannula through a lumen in the outer component, through which a mandrel may be placed. The outer component includes an internal boss that reduces its internal diameter, and the cannula includes fingers that extend distally. When the needle is inserted for biopsy, tissue enters the outer component and cannula. Moving the cannula forward causes the fingers to engage a surface of the internal boss, resulting in the fingers curving into the tissue. The fingers pinch the tissue while reducing or eliminating compression of the sample to provide an easier removal of the tissue from adjacent tissue, as well as providing a block or backstop keeping the tissue within the needle. Gaps are provided between the fingers to further reduce damage to the tissue sample.

  • Patent number: 9326784
    Abstract: A minimally invasive surgical assembly broadly includes an outer hollow needle which has an outer diameter of approximately 2 mm or smaller, and a coaxial surgical instrument having a shaft which extends through the outer hollow needle. The coaxial surgical instrument includes end effectors at the end of the shaft which are biased to an open position such that when the end effectors of the surgical instrument extend out of the needle they open, and they are closed by relative movement of the needle over them. The assembly preferably includes a first fixing element which is used to fix the relative location of the surgical instrument and the needle. The assembly also preferably includes a second fixing element which moves relative to the needle and is located on the outside thereof and which is used to fix the relative location of the needle to the patient.

  • Patent number: 9277981
    Abstract: The device comprises an injection system, which is made up of a rigid external tubular body (1) that enables it to be inserted into the abdominal cavity of a sow. This body is, in turn, covered by a sterile sleeve (2) that enables it to be used in different animals. A flexible duct (3) runs coaxially and its distal end connects with a bevelled needle (4) that permits insertion in the oviduct (12) at an angle of 45°. The proximal end of the flexible tube connects with a device (6) that includes a sheath (7) closed at the other end by a piston (8) that slides along the inside of the sheath and that enables the precision insertion of low-volume liquids.

  • Patent number: 9216020
    Abstract: An endoscopic surgical cutting stapler with a chain articulation is provided, in which a joint is implemented by a chain articulation, teeth are provided at two ends of a chain plate of the chain articulation, and teeth of adjacent chain plates in the same row are engaged. Through mesh transmission of engaged teeth of the adjacent chain plates in the same row, an angle of a most proximal chain plate of the chain articulation is gradually multiplied at several stages and transmitted to an end effector. The end effector can rotate for 90° with small drive motion of the operating mechanism, thereby achieving precise placement of the chain articulation after rotation. The end effector can be precisely aligned with a part to be cut and stapled, and a radius of curvature of the chain articulation can be significantly increased.

  • Patent number: 9192432
    Abstract: A surgical instrument includes a handle movable between first and second positions for transitioning an end effector assembly between states and to a third position for returning the handle. A latch arm coupled to the handle includes one or more engagement members. A latch block defines a guide track having a latching path configured to guide the engagement member(s) therealong, an engagement portion configured to engage the engagement member(s) to latch the handle in the second position, and a return path configured to guide the engagement member(s) therealong. A first step interdisposed between the latching path and engagement portion guides the engagement member(s) into engagement with the engagement portion and inhibits the engagement member(s) from returning along the latching path. A second step interdisposed between the engagement portion and the return path guides the engagement member(s) along the return path and inhibits the engagement member(s) from re-engaging the engagement portion.
